Title: Heat treatment method
Inventor: NORO NAOTAKA
IPC: H01L21/31
Filed: 1994-03-09
Abstract: PURPOSE:To improve the uniformity of heat treatment between wafers when a plurality of semiconductor wafers are collectively subgested to heat treatment, e.g, oxidation treatment in a vertical type reaction pipe. CONSTITUTION:A plurality of wafers W are put on a wafer boat 6 and loaded in a reaction pipe 2. The inside of the reaction pipe 2 is purged by using Ar gas. Oxidation treatment is performed by making O2 gas flow from above to below after the temperature inside the reaction pipe 2 becomes equal to a specified value. After that, N2 gas is made to flow from above to below, and an N2 gas atmosphere is set. Since the gases are sequentially supplied in the order of large specific weight as Ar gas O2 gas N2 gas, the O2 concentration change pattern from O2 concentration rise to fall in the upper part coincides with the shape of O2 concentration change pattern in the lower part. Hence the uniformity of the oxide film thickness between the upper part and the lower part is improved. The same effect can be obtained by supplying the gases in the order of small specific weight as N2 gas O2 gas Ar gas.

Title: Tape cartridge
Inventor: MIZUTANI HIKARI
IPC: G11B23/087
Filed: 1987-03-20
Abstract: PURPOSE:To prevent a tape from slackening during non-use by enabling a tape holding member to be changeable in its pressing pose and evading pose by operating only a slider to be opened and closed and setting up the tape holding member not in an immoderate way. CONSTITUTION:When the slider 9 is positioned forward in a closing position, i.e., when a tape cartridge is under the non-using condition, the rear end of a recess groove 40 is in contact with a releasing piece 39 in its pose pressing a tape guide 6, thus preventing the tape 4 from slackening off. Since then from this condition, when the slider 9 is operated to be opened backward, the front end of the recess groove 40 is brought into contact with the releasing piece 39 in a near end of its back stroke, so that the tape holding member 35 is changed over to the evading pose. By this method, the tape holding member 35 can be mounted without trouble, and the tape can be prevented from slackening at the time of non-use.

Title: Sensor for detecting water infiltration in optical fiber
Inventor: SAWANO HIROYUKI
IPC: G01F23/292
Filed: 1987-03-20
Abstract: PURPOSE:To permit exact and quick detection of outbreak of a water infiltration accident and a position where the accident breaks out by winding an optical fiber on a cord-like water absorptive body made of a water swellable material which swells volumetrically when the body absorbs water, thereby constituting a titled sensor. CONSTITUTION:This sensor 1 for detecting water infiltration is optical fiber is constituted by winding the optical fiber 3 at a specified pitch on the rod- shaped water absorptive body 2 made of the water swellable material. The water absorptive body 2 swells and expands volumetrically by adsorbing water in the event of the water infiltration accident. Then, the size thereof increases and the volumetric expansion of the water absorptive body 2 acts as side pressures on the optical fiber 3, thereby generating bending such as microbending in the optical fiber 3. An increase in the loss of the transmitted light by this bending is detected by measuring the reflected light such as backward reflected light of the light entered into the fiber from the input end thereof. The outbreak of the water infiltration accident and the position where the accident breaks out are thereby quickly and exactly detected.

When a condition, under which semiconductor atoms adsorbed in the substrate 11 migrate on the surface of the substrate for a certain time, is set, a structure periodic in a planar direction can be formed using a molecular beam epitaxial growth method or the like, that is, a superlattice layer vertical to the surface of the substrate 11 can be formed. A region 13 whose conductivity is opposite to that of the substrate 11 is provided onto the superlattice layer 12, and an electrode 15 and a high resistive layer 14 are formed. Being the thickness of a superlattice layer sandwiched between a p-type and an N-type layer is the average travel distance of carrier, and the thickness concerned can be controlled of the order of a few atomic layers and made constant. Being reversely biased, a photodetector of this design can be improved in response speed and minimum photosensitivity obtaining a high electric field with a low voltage.

Title: Dc power source unit
Inventor: FUJIHIRA KANAME
IPC: H02M3/00
Filed: 1986-03-26
Abstract: PURPOSE:To eliminate electric power loss and to heighten efficiency of DC power source by providing a relay contact between anode and cathode of an energy reverse emission prevention diode, and closing the relay contact at the time of normal operation. CONSTITUTION:At the time of normal operation in which a primary power source 1 is made, there is no voltage that biases a diode 18 sufficiently in normal direction, and current does not flow in a relay coil 17 and a relay contact 16 is on state. Accordingly, power supplied from the power source 1 is accumulated in an energy bank 9 not through an energy reverse emission prevention diode 2 but through a rush current prevention circuit passing through the contact 16. In the case where the power source 1 is in shortcircuited state and made off, input voltage of the bank 9 becomes higher potential than output voltage, and current flows in the coil 17. Thereby, the contact 16 becomes off in a moment and the diode 2 is released from short-circuited state, and prevents reverse emission of accumulated energy of the bank 9, and at the same time, becomes possible to supply specified electric power to a load 12 for a specified period.

Title: Voice encoder
Inventor: AKAMATSU MINORU
IPC: G10L19/04
Filed: 1988-03-22
Abstract: PURPOSE:To obtain an encoded voice of high quality by providing a total electric power calculator for input signal and a linear predicted value weighting multiplier which inputs the output of the input signal total electric power calculator, weighting a linear predicted value with an input signal total electric power value, and controlling a prediction gain. CONSTITUTION:The linear predicted value which is the output of a linear predicting device 6 and electric power which is the output of the input signal total electric power calculator 3 are led to the linear predicted value weighting multiplier 5, which multiplies the electric power by the linear predicted value from the linear predicting device 6 and thus makes the gain of linear prediction proportional to the electric power to control the prediction gain. Consequently, the prediction gain at the time of the input of a small signal is lowered to stabilize the operation of the linear predicting device and reduce an allophone, thereby obtaining the encoded voice of high quality.
